I ordered a laser module from eBay and the one i received looks nothing like the one i ordered :( . They are sending the correct one and also letting me keep the wrongly sent module. Although, i have no clue what it is, how to use it or anything about it really.

Any information about this module would be greatly appreciated :)







Thanks.
 





so you didn't get the one in the ebay link?
Post a pic of the one you did get:)

It is the same green module but with different wire connections. Mostly this one is used in a standalone lab module and the spring version one is used in a pen host.
 
3VDC (2*AA's)to the red and black. I hope you didn't buy it at the price on the link :)

so the yellow wire doesnt matter? i sure didnt haha. i got it for $21.99 but for some reason the seller relisted it at $125 lol :)
 
nope, i think the yellow is to monitor or control something(TTL?). but to get the laser to work you wont need it.

If it's for a lab module, the yellow wire would be for modulation. You _may_ need to connect it to + for the laser to turn on. Most modulation signals are logic level - 5V.
